Design on the Testing System of the Towing Tank

Considering the requirement of testing on ship powering performance, and the actual situation of the towing tank, a system, which contains the testing module of resistance performance, propeller on open water, self-propulsion and calibration, was designed. And a system software used for measuring ,controlling and analyzing date was written as well. Every modules’ main functions, test requirements and the realization forms were also put forward in this paper. Considering it not only meets the need of the model test mentioned already, but also fits the function expanding in the future, this system was designed to be modularized and scalable. I hope that it could give technical support to the researchers in ship performance and ship construction enterprises.
